To all whom/it muy concern: i

Be it known that I, EMIL `MALDE, a eitizen of the United States, residing at Portland, in the county of Multnomah `and State of Oregon, have invented eertainnew` and useful Improvements in Valves; and I do hereby declare the following to be a` full, clear, and exaetmdescription of the invention, such as will enable `others skilled in the art `to which it appertains tonmake and usethe same. This invention relates to improvements in valves, and has for its object toprovide an improved valve especially designed for use in connection with water gages of lOcomotives, although `it is not necessarily limited to suchuse. y 1 w Y y Another object isnthe provision of means for expeditiously adjusting the valve `including means whereby the valve may .be quickly and conveniently removed independently of theadjusting means to facilitate grinding, repair orreplacement."

lVith this and `other objects in view, the invention consists in the novel construction, combination and arrangementof parts as will 'be' hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which: i

Figure 1 represents a longitudinal {sec tional view through the valve, 1

Fig. 2 represents a sidegelevationthereof, partly in section, showing the valve in open position, and f Fig. o represents a transverse sectional f view on the line 3-3 of Fig. l. v

Referring to the drawing in detail, wherein similar reference numerals designate corresponding par-ts throughout the several views, the numeral 5 indicates the valve casing, which is formed with the internal chamber 6 communicating with the inlet and outlet ports 7 and 8, respectively. A cylindrical stem 9 is slidably supported in a tubular extension 10 fonmed integral with the casing 5 and is provided with a tapered or Abeveled inner terminal or valve 11 movalble against a 'restricted portion 12 of the' casing constituting a seat therefor. stem 9 of the valve is extended, eXteriorly of the casing 5 and a packing ring 13 is fitted upon the outer Iterminal of the eXtension 10 and is designed to prevent the Huid passing' through the valve casing from escaping around the stem 9.

The outer exposed terminal of the stem 9 The ` specificati@ bf revers Paten; ratentuuune 24, 191e. 1 yApplication fiikl March so, 1918. wserrialNo. 225,705.l

jacent the hand wheel V21 `is increased in diameter,` as indicated at 22,` toreceive the y rotatablesleeve 23 supported upon the red 20. y The sleeve 23 is conlined between col lars 211 secured in spaced relation upon the rod20.` W1 `1 Anpear 25.is rigidly secured to or `formed integral with the sleeve 23 and is formed lnits outer orlower terminal` with acurved slot 26, adapted lto receive the portion of the` valve stem 9 `intermediate the collar 141 and the head 15. 17 is formed with a slotQ?, communicating` vvithythe enlarged; `terminal 22 ot' the opening therethrough and` adapted to receive the ear 125, whereby the sleeve 28 is held against rotation when advanced in wardly toward the casing 5; 1 y

From the foregoing it is clearly evident that thevalve 11 may-be `convenientlywand accurately adjusted by the rod 20 and hand wheel 21, the screw threaded terminal 19 of the rod moving in the threaded portion 18 of vthe opening through the enlargement 17. Accumulations of dirtor other matter upon the working face of the valve 1.1,incident `to extended use of the valve, may `be quickly removed by adjusting the rod 20, so

as to move the valve against the seat 12 and subsequently turning the valve with a suitrelatively` sta-H The hollon7` enlargement ranged in spaced rela-tion to an integral head able tool inserted in the slot 16 of the head 15. When it is desired to remove the valve for inspection, or for any other purpose, the

screw threaded rod 20 is moved` outwardly so as to disengage the ear 25 from the slot 27. When the ear 25 is disengaged from the slot-,27, it may lbe swung outwardly so as to disengage the stem 9 and permit the latter, together with the valve 11 to he removed from the casing 5.

What I claim is: i 1

l. A valve structure including a casing vagainst said seat, a stem carried by the valve,

a screw threaded rod itted in said easing,l a sleevemounted upon said rod and rotatable Within said Casing, said rod being rotatable linsaid sleeve, means 4to normally .retain said` sleeve against rotary movement with relation' yto said easing, yand means carried by said'sleeve releasably engaging saidstem for adjusting Vthe latter together ywith the valve. 1
